If you expose yourself to the language you want to learn, you will achieve success much faster. Of course, stays abroad have the greatest impact, but you can also integrate a new language into your everyday life at home. For example, change a website you visit frequently or your cell phone to the target language. Listen to music, audiobooks, or podcasts in the respective language. Read foreign language books and newspapers. Watch movies and TV series with original soundtracks. Even if you don't understand every single word, daily exposure to the language will prove advantageous.
Thinking or talking to yourself in the language you are learning will also greatly accelerate your learning process. Try going over your appointments for the week or your shopping list in the target language, or tell yourself about your weekend.
Get in touch with international students at your university! For example, register with the buddy program offered by the RWU International Office and take an international student under your wing for a semester.
